Anybody else read Andrew Cook's articles?  There's a copy of part 1 at https://www.reddit.com/r/BitcoinMarkets/comments/274wbs/how_to_make_money_trading_bitcoin_day_1_of_5/ but there are 4 more parts, you'll have to search for them, the first 3 or 4 are the most important.

I'm trying to decide if this peak is over.  The last one hit $19,000 and some people have speculated this one would reach $20,000.  I jumped in at about $4,000 with $450.  If this is a peak it's much lower than I expected.  We had a few weeks of uncertainty that ended a couple weeks ago when it went from $8k to $12k.  This could be more of that.  There's power in reinvesting, but you need to wait for the price to drop.  Then you make x% profit on more capital, and keep reinvesting.  As long as it doesn't go below where you jumped in you're not losing money.

Since the mining difficulty factor is climbing beyond where it's practical to mine without free electricity like solar, it makes sense that the price is going up.  I was surprised the last low only got down to about $4k and not more like $400, but that's probably what the future holds.
